Hosta plant named ‘Paradise Power’

ABSTRACT

A distinct cultivar of Hosta plant named ‘Paradise Power’, characterized by its golden yellow leaf color; relatively compact plant habit; and lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta hybrid, and hereinafter referred to by the cultivar name Paradise Power.

The new Hosta was discovered by the Inventor in a controlled environment in Ter Aar, The Netherlands, as a whole plant mutation of the Hosta hybrid cultivar Sun Power, not patented, in 1994. Plants of the cultivar Sun Power have solid golden yellow-colored leaves whereas plants of the new Hosta have golden yellow-colored leaves with green margins.

Asexual reproduction of the new cultivar by divisions harvested in Ter Aar, The Netherlands, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Paradise Power have not be observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, irrigation amount and frequency, and/or fertilizer rate without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Paradise Power’. These characteristics in combination distinguish ‘Paradise Power’ as a new and distinct cultivar:

1. Golden yellow leaf color with green margins.

2. Relatively compact plant habit.

3. Lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hosta, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Hosta.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Paradise Power’ grown in a container.

The photograph at the top of the second sheet is a close-up view of a typical flowering stem of ‘Paradise Power’.

The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Paradise Power’.
